First assure your wheels don't slip.  Use materials with some friction.  Don't use elastic belts.  Better yet, use a different model, like mine with sails the fold up.  That should keep you busy.

The only way no wheel will slip is if the force applied is lower than the force needed to make the wheels slip.  So that will mean treadmill has not enough power to move at all.
Vehicle as it is designed is locked meaning wheels can not rotate.
That is what you see when front wheel only rotates is because the belt is stretchy so energy can be stored there.
If you use a belt that stretches less than less energy will be stored and then vehicle will move less at each charge discharge cycle.
If you make the front wheel have better traction than the back wheel so that back wheel slips first the vehicle moves in the direction that treadmill moves so right to left in my example.
So what you say is basically make this effects less visible. They will still be there even if less visible as without both energy storage and slip stick hysteresis the vehicle will not work.


When I first done the experiment my expectation was that vehicle will not move at all or maybe be dragged in the direction the treadmill is moving so I was fairly surprised as while same belt was used when you move the paper faster and you watch things happen at normal speed (no 5x slowed down with high speed camera) the motion looks fairly fluent and you can not see the stop and go behaviour.
I was lucky that belt was fairly stretchy as I moved the paper (treadmill equivalent) slower to try and see what happens and I barely noticed that front wheel was moving while the back wheel did not and then realized what happened. After taking that video that you also seen everything was even more clear.

In theory if you can not use energy storage and stick slip hysteresis you can not prove that vehicle can move from left to right against the direction of the force applied so whatever intuition you have is wrong. Both the theoretical analysis and the real world test shows that without energy storage and stick slip hysteresis this will not work.

Of course the wheels can move.  I've already explained how they will move. 

Whatever.  You clearly do not want to conduct a reasonable experiment.  You are like Andrea Rossi demonstrating the e-Cat.

You will need to twist the belt (infinity symbol) for the wheels to move freely as it is it is a locked gearbox. In order to move in any direction as it is it will require for wheels to slip.
You realized that with your sail vehicle when you added another set of wheels to reverse the direction.

In that the properties of the dielectric (insulator) and the geometry of the coaxial cable affect the energy transfer capabilities of the coaxial cable more than the core conductor does.

Really? If you replace the core by some plastic, what happens?
